Trail Marathons in May

Snow is mostly gone below treeline, and summer heat hasn't arrived. If you're picking a first trail marathon, these are some good choice. Looking for something longer, check out Ultramarathons in May.

Count back from race day

  • Late October: start the 10-week primer
  • Early January: start the 18-week plan
  • Late April: peak week
  • Mid-May: race day

Your training season. The primer carries you through the holidays. The build starts once the gyms empty out after New Year's, and the long runs stretch out with the days.

Masters Athlete Insights

The first hot day of the year always surprises people. Run a few midday sessions in your last four weeks so race day isn't the first.

Start the 16-week 50K plan · Not 26 weeks out yet? Begin with the 10-week primer.
